    Telnet to your router and do a 'ps -axf >> /tmp/mnt/output_of_ps.txt'
    Or you can do a prtsc (printscreen) on your computer, then use just
    'ps -axf' on your router-console.
    maybe that the command 'top' is available, if so - do a printscreen and copy your screen to any editor.
    On windows xp: start, run, cmd
    then telnet ipofyourasus
    then user: admin, enter
    passwd.: admin
    then you are on the console of your router - all linux commands should work.
    If interested you can install something according wengis howto......

    no prob at all - we can do it step by step -just let me know.
    I'll guide you and you'll see, linux is nothing special.
    And after a couple days, you'll become a regular linux user.
    It's just the starting.........

    Hi,

    Thought I might also jump on this response too The first time I notice there is a problem is from what ever PC I'm using. Skype seems to be the most affected by any network outages. I'm pretty sure what is happening is the router is rebooting but there mustn't be an actual power drop on the USB as the modem stays connected. The only way I can get it to reconnect is to unplug/replug the modem or to do a cold startup (i.e. full power down) of router. A normal reboot does not work.

    What exactly is the modem doing after

    -startup

    It does the flashing green thing (three quick flashes, searching for n/w I think), then goes to a slower blue flash and a blue solid light.

    -when online

    When the link is required it goes from a solid blue to a solid aqua.

    -which koppel FW

    I'm currenlty using 1.9.2.7-10-USB-1.69a but have had similar issues with 1.70a and 1.71.

    -is there any other device connected to usb?

    No it is the only USB device

    -after connection is lost: wait at least 5 minutes - do you get the connection again?

    I can see pppd stopping and starting again with a new PID and trying to connect. But I get "Connect script failed" in /tmp/chat.log. If the modem was actually doing something at the time I get it's output as well. For example if I am doing a email send/receive as it dies I can see my actual emails in /tmp/chat.log

    Contents of chat.log

    [admin@WL-001FC660CF29 root]$ more /tmp/chat.log
    ~!E^@^@(M-FA^@^@+^FZ^CBM-#M-5M-<sM-^B^CM-*^SM-:^L]M-!M-G}^M-^v#M-AM-^[P^PM-^@RGz
    ^@^@M-^Sa~Failed
    Connect script failed

    /tmp/resolv.conf is empty.

    -when connection is lost: can you post the output of 'top'

    See below, I've included a comparison with top when the connection is up.

    -is any other sw installed?

    Nothing except for base firmware.

    Top from when disconnected.

    @Malks

    Well, when your /etc/resolv.conf is emty it means, there is no connection.
    Hence we are able to detect a lost connection. First of all, we should find a way to reconnect without rebooting.
    Can you try the following when connection is lost:

    'killall pppd'

    It can take some seconds to reconnect....

    If it doesn't work, try:
    'reboot'

    further, when you have a working connection do a:
    'cat /etc/resolv.conf'
    and write down ip of nameservers. Then enter webif, ipsetting, wan&lan and enter under item wan dns servers your nameservers - apply & finish.

    keep me posted....

    Hi Newbiefan,

    And that's the core of the problem. The pppd actually determines there is no connection and detects that correctly. The problem is it tries to send it's AT commands to the modem as part of its connect script and instead of getting a response like 'OK' it gets the actual stream of data and so the connection fails. Doing a 'killall pppd' doesn't help as the modem stays connected. Even doing a reboot doesn't help as the USB port doesn't seem to get powered down as the modem stays connected after a reboot. A cold shutdown/restart does work though.

    Thanks for your input.

    Regards,
    Anthony.

    Funny, when I kill 'dial' , I get the pretty same behavior.

    So I would suggest to try:
    killall dial
    killall pppd
    reboot

    I think the website was having problems, as I tried your link and it didn't work, but it works now, so just try again.

    The link was working, i'm just confused on which FW i should use for my plain old WL500G (no deluxe, no premium....)

    Hi all,

    I had no problems running koppel fw with an E169 modem, recently i changed my modem for an E220 and i am facing the same problem as malks.

    Soft rebooting does not restore the connection, the only thing that helps is switching power off/on.
    I tried the watch_wan script from newbiefan, but did not help...
    Now i am trying to modify the script to send AT reset command to the modem before restarting PPPD. But it seems that using
    Code:
    echo "ATZ" >> /dev/usb/tts/0
    is not the good way to do this. Any hints ?

    Edit :
    Using
    Code:
    serialcomm /dev/usb/tts/1 <ATCOMMAND>
    i can send commands and read response from the modem. What is weird is that the log reports that ppd is using /dev/usb/tts/0 and i only get errors when trying to communicate with this device...


    Edit 2 :
    Here is my modified watch-wan script
    Code:
    #!/bin/sh
    #Script watch_wan, controls inet connection, when lost - a new dial in is performed
    #Improved script by newbiefan
    #Original script from member Anttu @ asusforum (wl500g.info)
    #published under GPLx (at your coice)
    #a good place to store this script is /tmp/local/sbin/watch_wan
    #this script read the content of file address stored anywhere
    #Content of file address is google.de yahoo.com aldi.de krone.at
    #File address should have at least one address
    #Version 0.2-04/2008
    
    
    maxad=0  #set maxaddresscounter to 0
    # read file addresses into a var called addresses and use them one by one
    #please change the dirs and filename as well as content to your needs
    addresses=google.de yahoo.com aldi.de krone.at   #adjust path if needed 
    #access each address to count how many they are
    for address in ; do
            let maxad=+1  #how many addresses in list
    #        echo 
    done
    #
    #choose any writeable directory and any name for your loglocation
    #loglocation=/tmp/harddisk/wan-watchdog#this is your logfile
    loglocation=/dev/null #if you don't want a logfile, send any message to linux-nirwana
    #
    
    i=1 #start with first address
    sleep 300
    while [ true ]; do  #endless loop 
    
    for address in ; do
      sleep 60#wait 60 seconds until next ping, change it as you want
      ping_resp=#ping address 1,2,3,4,5 aso
    #uncomment the next three lines if you need to control function of script
    #  echo -n .Web address:  >> 
    #  echo  >> 
    #  echo 
      if [  =  ]; then   #if ping is not successful then
          echo -n Connection lost at  >> 
          date >>  
          if [ -n 325 ]; then
             echo Stopping pppd >> 
             echo ------------- >> 
             killall pppd
            else   #if pppd is not running, reboot
             echo Rebooting, pppd is not running! >> 
             echo ------------------------------ >> 
             reboot
          fi
          sleep 60#just wait a bit longer to establish a connection again
      fi
     let i=+1
     if [  -gt  ]; then i=1; fi #end is reached, start again with counter
    done
    done
    I increased the initial delay to 300 seconds, as it seems that 60 secs was too short. Let's see if this helps.......

    Huawei E122 support?

    Hi I have a E122 modem from Huawei and think I heard it was very similar to the E220 but I have not had luck connecting it with instructions for E220.
    Does anyone know if it is possible?

    Thank you for any response
